Seismic random noise attenuation using modified wavelet thresholding
Annals of Geophysics, 2017 In seismic exploration, random noise deteriorates the quality of acquired data. This study analyzed existing denoising methods used in seismic exploration from the perspective of random noise. Wavelet thresholding offers a new approach to reducing random

Seismic Hazard Indicators in Japan based on Seismic Noise Properties
Journal of Earth and Environmental Sciences Research, 2023 The seismic noise recorded at the network of stations in Japan for more than 26 years (1997 - March 2023) is being investigated. The article is a continuation of the number of works in which the analysis was performed for 1997 - March 2021. New data for 2 years of follow-up observations, combined with a new approach to their analysis, provided ...
